Be it known that I, EDWARD W. CRABTREE, a citizen of the United States, residing at Hillsboro, in the county of Orange and State of North Carolina, have invented certain new and useful Improvements in a Safety Strap for Shipping Grates, of which the following is a specification.

moved in an unauthorized manner and yet tain novel features of construction, and in.

' like.

The present invention appertains generally to devices for strengthening, bracing, and locking shipping crates, and more part1cu larly to an improved strap which may be placed about the crate very quickly andwill be prevented from becoming very easily remay be quickly and easily'removed when desired by an initiated person. 7

Another very important object .of the m vention is to provide a device of this. nature which isexceedingly simple in its construction, inexpensive tomanufacture, efficient and reliable in use, strong and durable and otherwise well adapted to the purpose for which it is designed. v

With the above and numerous other objects in view as will appear as the description proceeds, the inventionresides in certhe combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is an elevation of a-crate showing my improved strap applied thereto,

Figure 2 is a perspective view of the strap, and

Figure 3 is a detail section taken on the line 33 of Figure 2.

Referring to the drawing in detail, it will be seen that A designates generally a crate of well known construction which is commonly used in shipping vegetables and the This crate has merely been disclosed so as to clearly demonstrate the utility of the invention, and it is' obvious that my improved device as will hereinafter be de ing thev two; .rectangularly d isposed. arms .3

and 4. The arm 3 is provided adjacent its terminal with an aperture 5 for receiving the looped end 6 of a link member 7. An aperture 8 is providedintermediate the ends of the arm 4. The terminaljof this arm 4 is bent to provide a sleeve 9. as is more clearly shown in Figure 3. The bottom strap member 2 includes the body intermediate portion having at its terminals the rectangularly disposed arms 10 and 11. The arm 10 is provided at its terminal with an aperture.

1.2 for receiving the other terminal loop 13' of the link member 7 An aperture 14 is provided in the arm 11 and receives the loop terminal 15 of another link member 16.-

The other end of'the link member 16is inii serted through the sleeve terminal 9 and extended through the aperture 8 and then bent When the device is initially applied tol the crate A the link member 16 is disen gaged from the arm, The link Imember 16 is straight, that is disengaged from the arm flf The strap'member 21s preferably applled transversely across the bottom, while the strap member 1 is applied transversely across the top, althoughthe arrangement of these strap members may be reversed. The link member 16 is then inserted through the sleeve terminal 9 and through the aperture 8 and bent downwardly over upon itself.

. It will thus be seenthat the device braces the crate and positively prevents the lid thereof from becoming accidentally open. The strap device also efficiently strengthens the crate and assists in preventing the same from breaking down as often happens owin to the rather rough usages to which said crate is put. It is preferable to construct the strap membersl and 2 of sheet metal, al-" able material may be utilized.

though any other suitable strong and dur- It'ls thought that'the construction, utility, and advantages of myinvention will now be clearly understood without a" more detailed description thereof. The present'embodiment has beendisclosed'in detailmerely by way of example since inpractice it attams the various features of advantageenumerated as desirable in the statement of the invention and the above description. It

will be apparent, however, that numerous sizes, and in the materials and in the combination and arrangement of parts may be resorted to Without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages I Having thus described my invention, What I claim as new and desire to secure by Letters Patent is A device of the class described including a U-shaped strap member, link members pivotally engaged with the terminals of said strap member, a second U-shaped strap member having one terminal pivotally engaged with one link member, and its other terminal formed in a sleeve and provided with an aperture so that theother link membe may be inserted through the sleeve and through the aperture and then bent over upon itself. 7

In testimony whereof I affix my signature.
